Halo Upmix and Halo Downmix Bundle
This bundle includes both Halo Upmix and Halo Downmix.
In the latest version, Halo Upmix now enables multichannel-to-multichannel upmixing, delivering new levels of versatility and time savings in the production of surround audio.
Available in Avid AAX, VST, and AU formats, Halo Upmix automates the creation of a stereo-to-surround, downmix-compatible upmix with unique centre-channel management and spatial density controls.
The plug-in adds a new set of algorithms for upmixing from multichannel audio (LCR, Quad (4.0), 5.0, 5.1, 7.0 and 7.1) to either 5.1, 7.1, or 9.1 (7.1.2). This expanded multichannel support means that Halo Upmix users have an even broader array of options for upmixing, while the upgrade also includes other modifications designed to enhance user operability and finesse the interface customisation process.
From naturally extracted and expanded soundscapes to full cinematic big-stage enhancement, Halo upmix delivers with intuitive ease, all the control you need to fine-tune your surround mix to perfection. With unique centre channel management, including switchable dialog extraction, Halo is perfect for all types of production from archive restoration and TV through to the full 7.1 Feature Film experience.
Halo Downmix provides precise surround control, versatile downmix balancing and mix monitoring for accelerating and enhancing your surround productivity. Halo Downmix is the glue that brings your workflow together, allowing you to deliver in surround and stereo with ease and without compromise.
- Standard and custom surround to stereo down mixing
- Surround re-balancing
- Simultaneous surround/stereo workflow
- Immediate and versatile surround/downmix monitoring
- Downmix rescue
- Surround restoration
Halo Downmix provides a highly creative solution for precise downmixing of feature-film or 5.1 mixes to stereo. Intuitive, visual controls for relative levels, timing, and direct vs. ambient sound balance allow uprecedented fine-tuning, delivering accurate downmixes that are no longer limited by typical in-the-box coefficients-based processes.
A standard downmix is usually generated by simply mixing together the surround output according to standard downmix coefficients, however, this can often lead to unsatisfactory results, particularly if legacy upmix practices have been used to generate the original surround mix. Halo Downmix can be quickly employed to mitigate these issues eg. controlling excessive diffuse sound from added artificial reverberation, or removal of delay artefacts introduced in the rear channels.
Halo Downmix can be quickly deployed to produce a more controlled, coherent stereo mix.
Typical applications include:
- Stereo Mix production for Television within a Surround workflow.
- Rapidly producing a controlled, precise stereo downmix of a 7.1 feature film.
- Generating a stereo mix from surround where no stereo recording exists.
- Producing stereo interim listening mixes in a surround workflow.
Fine Tune Existing Surround material
Adjust existing 5.1 or 7.1 mixes in surround-to-surround mode. Levels of individual channels, and balance of direct vs. diffuse sound can be adjusted to fine tune or re-balance existing surround audio where access to the original mix is not possible.
Parallel Surround/Stereo Downmix workflow
Halo Downmix can also be used in conjunction with the included Receive plug-in to enable a parallel surround/stereo workflow.
This workflow allows for rapid A/B listening checks between surround and stereo downmix.
- Optimising a surround mix for better stereo downmix (standard coefficients)
- Harmonising surround and stereo experiences, delivering a separate down mix
- Harmonising surround and stereo to produce a modified surround mix and stereo down mix
